Cura 15.04.2 generates print path that ruins print

Hi,

I am trying to print spiral vase. I use cura 15.04.2. Everything looks fine, except every few layers, cura creates a path for a print head to move back to start point..

This rapid movement back, goes in a path, that create some strings (retraction does not happen, even though it's set to 1.5mm). After some layers, print head just gets stuck to some of these strings and then steppers loose their steps and the print is ruined.

Is there any solution to this problem? I can't find a way to change that. Tried printing slower still same problem..

    I think there where more issues with spiralize in the later versions. Also an ugly vertical stripe on the outside wall. Try going back to cura 14.1 or 14.3 (rough guess). You can just run multiple cura's on the same machine.... (I'm on windows. Don't know for mac/linux)

    I've tried cura 14.01 - no changes, it still generates rapid movements from one side of the print to start point allong these narow ribs, this will again create strings that will eventually block heads movement and steppers will loose their steps..

    Any other ideas? Is this fixable at all? I cant print this

    @edis

    Can you show all your Cura settings ? Because I just tried now with Cura 15.04.2 and I don't have this problem ...

    You have to mark the tickbox on spiralise (below "black magic" in expert settings)

    Could you give a try with my stl file and see if this happens as well? Like i've wrote before - i scale only Z to 150 mm.

    It's exactly my file ... Spiral-02 :D

    But, if I scale down to 150mm ... I can't print (... probably because of my other settings and because I'm using a 0.6 nozzle)

    Anyway is never a good idea to scale an STL file ... you must preferably start from the 3D model and scale the model, then export in STL ;)

    I suppose you download from HERE and I'm quite sure that they were designed with OpenSCAD, so ... will be nice to find the .scad original files ;)

    With your help i think i have found a problem.

    If I scale whole model (uniform scale) - print path looks good (no extra moves around)

    If I scale only Z - it doesn't work anymore and it creates extra paths.

    Thank you for your help on this!
